Frequency-Dependent Boundaries and Excitations

In general, boundary and excitation parameters cannot depend on intrinsic functions. An exception is when a parameter depends on the variable Freq, which represents the solution frequency. The following boundary parameters can be assigned an expression that includes Freq:

• Impedance boundary - the Resistance and Reactance parameters.
• Finite conductivity boundary - the Conductivity parameter. If a material is specified, the conductivity of the material can be frequency dependent.
• Secondary boundary - the Phase parameter.
• Lumped RLC boundary - Resistance, Inductance, and Capacitance parameters.
• Layered impedance boundary - materials assigned on layers can be frequency dependent.
• Anisotropic Impedance boundary - Resistance and Reactance parameters.
  Note:

  Dependence on Freq is supported for single-frequency solutions and for Discrete and Interpolating frequency sweeps. If a Fast sweep is requested, the solution will be valid for the center frequency, but may not be valid at other frequencies.
